 H beam welding

  1.  H BEAM WELDING equipments and technical parameters

 

2.1. Structure principle

      H beam welding machine is mainly composed of gantry frame, weld arm and tool carriage, welding gun tracing device, welding flux handling system, electric controlling system and power source for submerged arc welding (Also deployed with two sets of auto submerged welder MZ-1000). The function of gantry frame is to support every part and drive every part move when welding.  There are two moving beams at the bottom, which was moved on steel track drive by two sets of AC motor through decelerator. The moving speed of gantry frame can be adjusted by frequency converter according to your request. This machine has the function of quick return. There are two pairs of guide wheels which are close to side of steel track to insure the machine move steady. The operation platform set up between two bearer carriers. Welding arm and tool carriage are installed on gantry frame, on tool carriage there are a few groups of wheel which abut against tracks. Tool carriage can be moved left and right manually through gear worm decelerator—rack-and-pinion. Welding arm can be moved up and down through motor---gear worm decelerator---rack-and-pinion driving. Welding gun tracing device is installed at the bottom of welding arm, wire feeder is installed on welding gun tracing device, welding head always aim at welding seam and keep a certain clearance. A pair of guide wheels abuts against two sides of welding seam, when welding seam curve to the left or right, the cross slide plate above guide wheel will be adjusted to left or right accordingly through the function of spring; when welding seam curve to up or down, the cross slide plate will be adjusted to up or down by guide wheel driving by the elasticity of cylinder; the whole welding gun tracing device can be adjusted by turning slightly; also welding gun manual fine adjustment for right and left are also set. Welding flux handling system is composed of welding flux bucket, welding flux recovery machine, they are installed on two welding arms respectively, and two sets of welding flux recovery machine are put on platform of gantry frame. Welding flux are flowed to welding seam through gate of welding flux bucket, welding head follows to weld. Welding flux recovery pipe regain remainder from back of welding head to tube, through screen mesh to screen, then into welding flux bucket through gate, at the same time, dust is imbibed into welding flux bucket, chunk of welding flux are left in recovery tube. Electric controlling system is composed of one electric controlling system and two operating box, controlling box is installed on moving beam of gantry frame and two operating boxes are set in the middle of gantry frame.
